System for the detection and localization of defective lamps of an urban lighting network
First Claim
1. A unit for detection, localization, and signalizing of functional defects of each lighting unit in a lighting network divided into zones (1,2,3,4), particularly a public lighting network, comprising a zone supply line coming from a cabinet (5,6,7,8), with the zones furthermore each being connected with a central electrical supply and with a central monitoring computer (17) in a control room (18), characterized by the fact that said unit comprises, for each zone:
- an emitter module (21) with which each street lamp is equipped, said emitter module being equipped with a detector (23) for detecting current consumption and for emitting a detections signal characteristic thereof; and
a receiver module (22) managed by means of a microprocessor which transmits a defect signal to the control room over a telephone line connecting each zone to the monitoring computer (17), for the purpose of intervention by a maintenance team.

Abstract
A unit for detection and signalizing of functional defects for public lighting. A unit characterized by the fact that it comprises, for the one part, an emitter module (21) with which each street lamp is equipped, preferably located in its post, at the level of the junction box, the emitter module being equipped with a detector for current consumption (23) using the alternative network of the supply line as the carrier of a detection signal, and for the other part, of a receiver module (22) located in the supply cabinet of the same zone, this receiver module managed by a microprocessor which transmits a defect signal to the control room over a telephone line. This invention is of interest for manufacturers and installers of materials, equipment and components for public lighting.
